PVB中间膜在上海的需求价格弹性分析数据

为更好了解不同区域的顾客对PVB中间膜的市场需求情况，我单位对不同规格的PVB膜的需求弹性数据进行采集计算。采集不同规格的PVB膜在某一时间段的需求数据和价格数据，得到该PVB膜的需求价格弹性本数据包含的时间段为2021年1月至2023年6月，采集了44种PVB中间膜（如厚度0.38、0.76、1.14、1.52mm的透明、乳白、浅灰等各颜色）在上海内的需求数据和价格数据。如果其需求量变动的比率大于价格变动的比率，那么说明其富有弹性，说明顾客对于价格变化的敏感程度，弹性越大，需求对价格变化越敏感，本行业所有企业可以适当的降低其价格来获得较多的收益。如果其需求缺乏弹性，本行业所有企业可以适当的提高价格来获得较多的收益。该项数据对本行业所有企业的市场营销决策有重要意义。1.数据采集：采集了44种规格的PVB中间膜在2021年1月至2023年6月的需求数据和价格数据，按照区域进行整理归纳，得到各规格的PVB中间膜在上海内的需求量变动数值和价格变化数值。 2.算法规则：对采集得到的数据按照如下公式进行计算：需求弹性系数Ed=-(△Q/Q)÷(△P/P），得到需求弹性系数。式中：Q表示产品的需求量，单位为份；P表示产品的价格，单位为元；△Q表示需求量同比变动值，单位为份；△P表示价格同比变动值，单位为元。取需求弹性系数的绝对值|Ed|作为分析数据时的参考系数。 3.数据分析：根据|Ed|的数值可分析该插座的需求价格弹性。（1）|Ed|=1（单位需求价格弹性），说明需求量变动幅度与价格变动幅度相同；（2）1<|Ed|<∝（需求富有弹性），说明需求量变动幅度大于价格变动幅度；（3）0<|Ed|<1（需求缺乏弹性），说明需求量变动幅度小于价格变动幅度；（4）|Ed|→0（需求完全无弹性），这表示不管价格怎样变动，需求量总是固定不变；（5）|Ed|→∝（需求完全有弹性），表示在既定价格之下，需求量可以任意变动。

To better understand the market demand for PVB interlayer films from customers across different regions, our organization collected and calculated demand elasticity data for PVB films of various specifications. We collected demand and price data of PVB films of different specifications over a specific period to derive their price elasticity of demand. The dataset covers the period from January 2021 to June 2023, and includes demand and price data for 44 types of PVB interlayer films (such as transparent, milky white, light gray and other colors with thicknesses of 0.38, 0.76, 1.14, 1.52 mm) in Shanghai.

If the ratio of change in quantity demanded is greater than the ratio of change in price, the demand is considered price-elastic, which reflects customers' sensitivity to price changes: the larger the elasticity coefficient, the more sensitive the demand is to price fluctuations. All enterprises in this industry can appropriately lower their prices to gain higher revenue. Conversely, if the demand is price-inelastic, all enterprises in the industry can appropriately raise prices to obtain more revenue. This dataset is of great significance for the marketing decision-making of all enterprises in the industry.

1. Data Collection: We collected demand and price data for 44 types of PVB interlayer films from January 2021 to June 2023, and organized and summarized the data by region to obtain the year-on-year changes in quantity demanded and price changes of each specification of PVB interlayer films in Shanghai.

2. Algorithm Rules: The collected data were calculated using the following formula to obtain the demand elasticity coefficient Ed:
Ed = -(ΔQ/Q) ÷ (ΔP/P)
Where: Q represents the quantity demanded of the product, in units of pieces; P represents the price of the product, in yuan; ΔQ represents the year-on-year change in quantity demanded, in units of pieces; ΔP represents the year-on-year change in price, in yuan. The absolute value of the demand elasticity coefficient |Ed| was taken as the reference coefficient for data analysis.

3. Data Analysis: The price elasticity of demand for PVB interlayer films can be analyzed based on the value of |Ed|:
(1) |Ed| = 1 (unitary price elasticity of demand): indicating that the magnitude of change in quantity demanded is the same as that of change in price;
(2) 1 < |Ed| < ∞ (price-elastic demand): indicating that the magnitude of change in quantity demanded is greater than that of change in price;
(3) 0 < |Ed| < 1 (price-inelastic demand): indicating that the magnitude of change in quantity demanded is smaller than that of change in price;
(4) |Ed| → 0 (perfectly inelastic demand): meaning that the quantity demanded remains fixed regardless of price changes;
(5) |Ed| → ∞ (perfectly elastic demand): indicating that the quantity demanded can change arbitrarily at a given price.
